Phys.org / Warming unlocks ancient carbon in Tibetan permafrost, triggering climate tipping point
A new study in Nature Communications finds a critical climate tipping point in Tibetan permafrost ecosystems. Warming of 2–4 degrees Celsius triggers a self-reinforcing cycle of carbon release that could significantly accelerate ...
Phys.org / Could the Milky Way's missing mass be hiding in a swarm of interstellar comets?
3I/ATLAS has caused quite a stir over the last year, inviting astronomers to update what they know about other solar systems as well as our own. However, this third interstellar visitor may have an unexpected impact on our ...
Phys.org / Atlantic 'cold blob' caused by weakening ocean current system that's likely nearing a tipping point, reanalysis finds
A part of the Atlantic Ocean, just south of Greenland and Iceland, has been cooling off while the rest of the world gets hotter. This enigmatic patch is often referred to as the "cold blob" and scientists have been trying ...
Phys.org / Remote work is taking its toll on the mental health of American workers, researchers find
Working from home comes with some major pluses. It's more flexible, there's no more pesky commute, work-life balance improves, and you can even stay in your pajamas all day if you want. But according to a major study of more ...
Phys.org / Birth rates are declining in most of the world—here's why it really matters
Birth rates have been declining worldwide since the peak of the post-Second World War baby boom. Birth rates have now reached below replacement in most of the world, including Australia. Put simply, populations on average ...
Phys.org / Wonderwerk Cave bones reveal possible fire use by human ancestors 1.79 million years ago
The discovery of fire was a major milestone in human evolution, giving our ancestors a way to stay warm, ward off predators, and eventually start cooking food. But exactly when this first happened is still intensely debated, ...
Phys.org / Violating the 3rd law of black hole mechanics in vacuum gravity
Black holes, regions in space where gravity is so strong that nothing can escape, have been widely studied over the past decades, due to their unique and intriguing properties. Einstein's theory of general relativity predicts ...
Phys.org / Most detailed map of the universe's hidden magnetic fields released
The largest magnetic map of the universe ever produced—five times larger than all previous efforts combined—marks the beginning of a new generation of research into intergalactic magnetism. Magnetic fields influence how galaxies ...
Phys.org / Scientists lose critical climate record as ocean observatory will go dark under Trump funding cuts
A portion of one of the most ambitious ocean monitoring networks ever built will go dark this month when scientists board a research vessel and motor off the Oregon coast to pull a research buoy from deep out of the Pacific.
Phys.org / Are JWST's early, overmassive black holes just normal-range outliers?
Ever since the JWST revealed a population of SMBH in the early universe that were overmassive, scientists have been working hard to explain them. These black holes existed when the universe was only about 2 billion years ...
Medical Xpress / AI-designed universal vaccine clears first human trial, targets future coronavirus threats with needle-free delivery
The first human clinical trial of a universal Sarbeco coronavirus vaccine, developed by the University of Cambridge and spin-out DIOSynVax (DVX) Ltd, has shown that the vaccine is safe and has no significant side effects.
Phys.org / Quantum circuits help AI overcome memory limitations with minimal new parameters
For millions of people, chatbots powered by large language models (LLMs) are now a key feature of everyday life. These AI systems are growing at a rapid pace, but scaling them up is becoming increasingly costly and resource-intensive.
